Despite a mauvais forecast bout 20 keen girls arrived at Bas Cuvier. We had one of the best warm-ups ever with parcour expert Thomas, who had us leaping and vaulting, and learning to land properly. Then we found a brief window of dry before the rain set in, but that left us enough time to work out 3 different betas for one of the hardest 6b+s in the forest for shorties, Hier Encore. When it really became too wet to climb, we all filed to Arbonne la Foret and climbed at Blocage.
Rain sucks, but broken holds suck even more. Remember, never climb on wet rock in Fontainebleau.
The sandstone becomes brittle, and pulling on it will ruin classic problems. Drying it doesn't help, because it's still wet and weak inside.
All you can do is wait for better conditions.
